Local fix

• This issue can be worked around using the -Dreflect.cache=false
  option. Note however that this will have a performance impact
  when reflection is heavily used.
  

Problem summary

• The problem is caused when a reflect object's annotations are
  parsed after its class has been redefined or retransformed.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR5
  .
  The JVM has been updated to flush the reflection cache when a
  class is redefined or retransformed.
  

Temporary fix
